following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out
differences in the way syscall numbers are printed on different platforms.
This gets rid of seven "DDD" fixme-style comments.
- This also meant that Darwin syscall numbers are now printed in a
non-ambiguous way -- previously Unix, machine-dependent and diagnostic
syscalls were all printed the same way, even though their numbers overlap.
Now each number is prefixed with "unix", "mdep", etc. And Mach trap
numbers aren't printed as negative numbers now that they have a "mach"
prefix.
- Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two
parts, one suitable for inclusion in asm files, one suitable for inclusion
in C files; in both cases the latter includes the former. This makes
this module more like other modules that have asm-only components (eg.
m_transtab); it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and
tests to be removed.
- Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed,
and renamed some of the existing ones to make their meanings clearer.
- Added comments on the encoding of Darwin syscall numbers so it's
possible for mortals to understand without reading the kernel code..

I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.
